barcode scanner: scans barcodes and looks it up on the internet.
yelp: favorite app lol, find good restaurants around you using your gps.
rotten tomatoes app: to see if a movie is worth watching
Where's my droid: if your phone is on silent or sound is low, you send a text to it with a specific keyword from another phone and your phone starts ringing on the highest volume.
Retro Camera: takes retro artsy pictures
FX camera: essentially the same as retro camera, has options like fisheye, polaroid and andy warhol.

Yea, that's the one thing I found annoying to start was that most phones I had would have one giant settings menu for everything. With Android, it's like each ap or whatever has its own settings menu. I guess it makes more sense, and is similar to a computer in that way, but it's just like going from phones before it takes a little to get used to.

But now any time I get/open a new ap, I immediately hit the settings button to see what's in there haha.
